Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100228, here are decompositions:

59 + 100169 = 100228
179 + 100049 = 100228
239 + 99989 = 100228
257 + 99971 = 100228
347 + 99881 = 100228
389 + 99839 = 100228
419 + 99809 = 100228
461 + 99767 = 100228

Showing the first eight; more decompositions exist.
